The draft genome of Primula veris yields insights into the molecular basis of heterostyly

, 2020
Background The flowering plant Primula veris is a common spring blooming perennial that is widely cultivated throughout Europe. This species is an established model system in the study of the genetics, evolution, and ecology of heterostylous floral ...

The structure and allelic diversity of the self‐incompatibility locus (S‐locus) in diploid potatoes inferred from genome sequences and transcriptome data from styles and pollen

The Plant Genome, Volume 18, Issue 4, December 2025.
Abstract Gametophytic self‐incompatibility (GSI) is a reproductive strategy to prevent inbreeding and promote outcrossing. Studies to understand molecular and evolutionary aspects of the self‐compatibility (SC)/self‐incompatibility (SI) system in the Solanaceae have been conducted using several genera including Petunia Juss., Nicotiana L., and Solanum ...

Identifying genetic markers linked to distyly in Linum tenue [PDF]

, 2021
Heterostyly is an adaptation designed to minimise inbreeding and promote outcrossing in plants, defined by the discontinuous variation in the lengths of pollinating organs between distinct morphs in a population.

Reversibility of sex changes in the plant kingdom: more important than we thought?

Biological Reviews, Volume 100, Issue 6, Page 2199-2216, December 2025.
ABSTRACT Compared to animals, plants show a wide range of reproductive strategies with different degrees of sex separation (e.g. dioecy, monoecy, hermaphroditism). While sex expression was previously thought to be genetically determined and fixed in plants, accumulating evidence suggests that sex expression can change reversibly even within one ...

Reproductive systems of Hohenbergia Schult. & Schult.f. (Bromelioideae: Bromeliaceae) endemic to the Atlantic forest

Nordic Journal of Botany, Volume 2025, Issue 9, September 2025.
Many species of the Bromeliaceae are under threat due to the fragmentation and anthropogenic pressure affecting the Atlantic Forest highlight the need to conservation efforts. The genus Hohenbergia deserves special attention in this context, as the Hohenbergia stellata complex includes endemic species that rely on diverse reproductive strategies, which

Influence of sex‐organ positions on pollen transfer and self‐interference in plants with stylar polymorphisms: An experimental approach using three‐dimensional printed flowers

Functional Ecology, Volume 39, Issue 9, Page 2526-2538, September 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Heterostylous plants are defined by the reciprocal positioning of stigmas and anthers in floral morphs—a trait proposed by Darwin to enhance the efficiency of disassortative (intermorph) pollen transfer.

Genomic studies in Linum shed light on the evolution of the distyly supergene and the molecular basis of convergent floral evolution

New Phytologist, Volume 247, Issue 6, Page 2964-2981, September 2025.
Summary Distyly, an example of convergent evolution, is governed by a supergene, the S‐locus, in several species. Recent studies highlight similar genomic architectures of independently evolved S‐loci, but its mode of origin and whether similar regulatory pathways underlie the convergent evolution of distyly remains unclear.

B‐class gene GLOBOSA – a facilitator for enriched species diversity of Salvia in the New World?

Plant Biology, Volume 27, Issue 3, Page 333-346, April 2025.
Analysis of B‐class genes of flowering in Salvia revealed a duplication of DEFICIENS in the whole genus and a geographically restricted duplication of GLOBOSA in the New World, correlating with enhanced species richness in the Americas. Abstract The genus Salvia, comprising around 1000 species, half of which are found in the New World, belongs to the ...

Heterostyly promotes disassortative pollination and reduces sexual interference in Darwin's primroses: evidence from experimental studies

, 2014
Different strategies to reduce selfing and promote outcrossing have evolved in hermaphroditic flowers. Heterostyly, a complex floral polymorphism that occurs in at least 27 families of angiosperms, is hypothesized to achieve both goals by optimizing ...
